Heat Pump Repair in Columbine

In a dual fuel system, an outdoor sensor tells the thermostat when to stop using the heat pump and start the furnace. Common problems we find in Columbine homes: the outdoor sensor was never connected, the thermostat is set up as a heat-pump-only system, or the changeover is set at a temperature that leaves the heat pump idle most of the winter. Each one can make the system feel broken when the equipment is fine.

We confirm the wiring, read the sensor against a thermometer and set a changeover point that fits your equipment and rates. Our dual fuel guide explains how that point is chosen.

Some frost is normal, and so is a defrost cycle every so often when the outdoor fan stops and steam rises off the coil. Repair calls start when ice covers the coil and won't clear, when vents blow cool air in heat mode, or when the outdoor unit runs but nothing changes indoors.

Solid ice usually points to a defrost sensor or board, a failing outdoor fan or low refrigerant. Cool air in heat mode points to the reversing valve, the solenoid coil on it, or a thermostat that isn't sending the heat signal. A unit that runs with little effect may be low on charge from a slow leak. We pressure test and use electronic leak detection before recharging.

In homes from the 1960s and 70s, the heat pump is often far newer than the furnace whose blower moves its air. When that blower motor weakens, the heat pump loses airflow, its pressures climb and it may trip off. We check the blower and its capacitor as part of a heat pump call, and we'll point out if the furnace is close to the end of its life. That matters for planning: if the furnace has only a few winters left, it can make sense to replace both together rather than pay for a heat pump repair now and a furnace later. If the furnace is sound, a targeted repair to the heat pump is usually the better value.

Hail is another outdoor risk in this part of the Front Range. Flattened fins on a heat pump reduce performance in both heating and cooling seasons.

Because there's no city government here, the county does the permitting: Jefferson County Building Safety for most addresses, and Arapahoe County handles the small portion that lies in Arapahoe. We figure out which applies.

We put a replacement quote next to the repair quote whenever the failure is a compressor, a big leak or a valve on equipment that's already getting old. Incentives for that replacement include $1,500 from Power Ahead Colorado (the application has to go in before installation) and Colorado's $1,000 credit. The federal 25C credit ended after 2025.
